Simple Vs Technical Mode
The mode switch on the scenario page changes how much control the app exposes. The right choice depends on how confident you are with the assumptions and how much you need to fine-tune the scenario.
What Simple mode is for
Simple mode is the guided path. It keeps the scenario editor focused on the most important inputs and avoids loading the screen with advanced controls too early. If you are still working out the broad shape of the system, this is usually the better place to begin.
That does not mean the mode is too basic to be useful. It is meant to help you get to a sensible first result without forcing you to manage technical settings that you may not yet need.
What Technical mode is for
Technical mode reveals more advanced battery and solar-side controls. It is useful when you already understand the battery behaviour, recharge assumptions, or solar-side detail you want to model more directly.
The extra fields are there for a reason. They are not there to be filled in automatically for the sake of it. If you do not yet know why a technical field matters, Simple mode is often the safer place to stay until the broader setup is clear.
When to stay in Simple mode
Stay in Simple mode if you are building your first version, if you mainly want a grounded planning result, or if you are still testing the broad direction of the setup. It helps reduce noise and lowers the risk of introducing unnecessary assumptions too early.
When to switch to Technical mode
Switch to Technical mode when you already understand the system well enough to justify more control. That might happen when you are comparing battery behaviour more carefully, adjusting solar-side assumptions, or working through a scenario that needs more than the guided defaults.
A useful habit is to get one sensible version working in Simple mode first, then branch into a new version if you want to explore deeper technical changes. That keeps your first result grounded while still leaving room for more advanced comparison.
The most important rule
Do not choose Technical mode just because it looks more capable. Choose it because you know what extra control you need and why it matters to the scenario.
If you only need a good planning answer, Simple mode is often the stronger choice. If you need deliberate control over advanced behaviour, Technical mode becomes useful.
